## Materiality and Audit Risk

### Core Concept: Inverse Relationship

Materiality and Audit Risk have an inverse relationship:

Audit Risk high → Auditor sets lower materiality
Audit Risk low → Auditor sets higher materiality

### When Is Materiality Considered?

Materiality is considered at three stages throughout the audit:

Stage	Standard
1. Identifying & Assessing ROMM	SA 315
2. Determining Nature, Timing & Extent of Further Audit Procedures	SA 330
3. Evaluating effect of uncorrected misstatements on opinion	—

### What Makes a Misstatement Material?

A misstatement (including omissions) is material if, individually or in aggregate, it could influence the economic decisions of users of financial statements.

Judgements about materiality are affected by both:

Size of the misstatement
Nature of the misstatement

### Whose Needs Count?

Materiality is based on common financial information needs of users as a group
Effect on specific individual users is not considered

Worked example

### Example 1

A company has a Rs. 50 lakh error in depreciation. Even if audit risk is low overall, the auditor must judge whether Rs. 50 lakh (individually or combined with other errors) could influence a bank's lending decision. This is a materiality judgement — both size (Rs. 50 lakh) and nature (depreciation affects asset values) matter.

### Example 2

An auditor sets overall materiality at 0.5% of revenue (Rs. 10 lakhs). Mid-audit, the team discovers fraud indicators, increasing audit risk. In response, the auditor lowers materiality to Rs. 6 lakhs so smaller misstatements are not missed. This demonstrates the inverse relationship in practice.

⚠️ Common exam mistakes

Treating materiality and audit risk as having a direct (positive) relationship — they are inversely related: higher audit risk demands lower materiality
Thinking materiality is only about rupee amount — nature also matters (e.g., even a small bribe payment may be material by nature regardless of amount)
Applying materiality to protect specific individual users — it must be assessed based on the common needs of users as a group
Ignoring the aggregate effect — individually immaterial misstatements can be material in aggregate and must be evaluated together

The auditor shall apply materiality when identifying and assessing the risks of material misstatement (SA 315) and when determining the nature, timing and extent of further audit procedures (SA 330), and in evaluating the effect of identified misstatements on the audit and of uncorrected misstatements, if any, on the financial statements.
